Embodiment Construction

[0021] A fuselage shell includes a skin substrate and a protective coating, the protective coating includes one layer of zinc yellow acrylic polyurethane primer and two layers of fluorocarbon topcoat. The dry film thickness of the zinc yellow acrylic polyurethane primer is 16 microns, the dry film thickness of the middle fluorocarbon topcoat is 38 microns, and the dry film thickness of the outer fluorocarbon topcoat is 54 microns.

[0022] The protective coating is formed by spraying a paint on the surface of the skin substrate, and the paint includes a fluorocarbon paint. Preferably, the A component of the fluorocarbon paint includes the following components: by weight, high hydroxyl fluorine-containing acrylic resin 61- 65%, color filler 20-26%, nano-magnesia 3%, nano-titanium dioxide 3.5%, leveling agent 1%, defoamer 0.8%, dispersant 1.2%, catalyst 0.5%, solvent 3-5%. More preferably, the fluorocarbon coating A component includes the following components: by weight, high hy...

Abstract

A fuselage shell with a protective coating comprises a skin base material and a protective coating, the protective coating comprises a layer of a zinc yellow acrylic polyurethane primer paint and two layers of a fluorocarbon finishing coat, the A component of the fluorocarbon finishing coat comprises the following components: high-hydroxy fluorine-containing acrylic resin, a color filling material, nanometer magnesium oxide, nanometer titanium dioxide, a levelling agent, an anti-foaming agent, a dispersant, a catalyst and a solvent. The fuselage shell provided by the invention is capable of being relatively well adaptive to current increasingly rigorous flight condition and improving flight security.

Description

technical field [0001] The invention relates to a fuselage shell with a protective layer. Background technique [0002] With the application of aluminum, magnesium and other alloy materials and composite materials in the aircraft manufacturing industry, the performance of the aircraft, especially the flight speed, has been greatly improved. Now the flight speed of the aircraft can exceed 1km / s. Since the friction force on a moving object is proportional to the square of the speed, the increase in flight speed puts forward higher requirements on the performance of the aircraft shell, especially temperature resistance, UV resistance, freeze-thaw cycle resistance, and air resistance. Abrasion resistance, rain erosion resistance, etc., so it is usually necessary to install a protective coating on the fuselage shell of the aircraft. This coating is generally formed by spraying paint, but the existing conventional coatings are difficult to meet the increasingly stringent requireme...
